[ http://issues.apache.org/jira/browse/HTTPCLIENT-596?page=comments#action_12426675 ] Roland Weber commented on HTTPCLIENT-596: -----------------------------------------
Hello Arnaud, NIO is not an option for HttpClient, which is JDK 1.2 compatible. Oleg is working on NIO support for HttpComponents (4.0). Starting an extra thread for each request sounds like a lot of overhead to fix a problem which most people don't have. You can run an extra thread in your application, can't you? cheers, Roland > read() on the stream returned by HttpMethod.getResponseBodyAsStream() cannot > be simply canceled with Thread.interrupt > --------------------------------------------------------------------------------------------------------------------- > > Key: HTTPCLIENT-596 > URL: http://issues.apache.org/jira/browse/HTTPCLIENT-596 > Project: HttpComponents HttpClient > Issue Type: Bug > Components: HttpClient > Affects Versions: 3.0 Final, 3.0.1 > Environment: Windows XP > Reporter: Arnaud Masson > > I have a working thread that needs to download some big file with > HttpMethod.getResponseBodyAsStream(). > A swing component displays a progress indication and has a "stop" button. > When the stop button is clicked by the user, I would like to stop the > download as soon as possible, so I call interrupt() on the working thread > from the EDT, which should throw an InterruptedException or > InterruptedIOException inside the working thread. > But the read() operation on the stream returned by > HttpMethod.getResponseBodyAsStream() is not interrupted. > The working thread stacktrace is: > SocketInputStream.socketRead0(FileDescriptor, byte[], int, int, int) > //<--------- blocking > SocketInputStream.read(byte[], int, int) line: 129 > BufferedInputStream.fill() line: 218 > BufferedInputStream.read() line: 235 > ChunkedInputStream.getChunkSizeFromInputStream(InputStream) line: 249 > ChunkedInputStream.nextChunk() line: 220 > ChunkedInputStream.read(byte[], int, int) line: 175 > AutoCloseInputStream(FilterInputStream).read(byte[], int, int) line: > 111 > AutoCloseInputStream.read(byte[], int, int) line: 107 > ... > I know that the JRE SocketInputStream doesn't support interrupt() but > HttpClient should hide this problem. > A workaround is to use request.abort() but it should be possible to cancel a > thread without knowing on what it is blocked. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
